ABSTRACT:
An injection laser of the multilayer planar type, such as, heterostructure GaAs:GaAlAs lasers are provided with offset geometry in the configuration of the stripe on surface of the device to stabilize the propagating optical beam such that the power output versus current pumping characteristic is linear over an extended range of operating currents. Many types of stripe offset geometries are disclosed which contribute in various degrees to such transverse mode stabilization.
